. 18 Claims. (01. 83-62) This invention relates to a machine for furnishing shaved ice or chipped ice as need therefor may occur, and the primary object of the invention is the provision of a durable and compact machine for the purpose specified whichmay be easily and quickly set up for use in a comparatively small space and will permit through a minimum expenditure of manual labor, ice shavings or ice chips to-- be obtained in amounts desired with the shaved ice and the ice chips keps separately and either dispensable from a common discharge. Another object of the invention is the pro vision of a machine of the above stated char-" A further object of this invention'is the provision of a machine of the character stated which embodies a portable collection unit in which the shaved ice and ice chips are sepa rately contained and which may be easily car-' ried from place to place and includes means for dispensing either the shaved ice or the ice chips into different kinds of containers.

With these and other objects in view as will become more apparent as the description pro-- ceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

- For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation illustrating an ice machine constructed in accordance with my invention. I

Figure 2 is a front elevation illustrating the device.

Figure 3 is a fragmentary longitudinal sectional view illustrating the cutting mechanism of trating the mounting for the cutting mechanism and the drive means for said cutting mechanism. Figure 8 is a top plan view of the collection unit.

Figure 9 is a fragmentary sectional view illustrating the mounting of the knives of the cut-- Figure 12 is a fragmentary sectional view illus- I trating a friction brake for the lever of the ratchet mechanism.

Referring in detail to the drawings, the numeral 5 indicates an elongated cabinet, one end of which is fully open to permit the cabinet to be loaded with a block of ice. The open end of the cabinet forms the front of the latter and is equipped with a door 6 mounted on the cabinet by hinges I and held in closed position by latches 8 operable from the exterior of the door.

v The cabinet 5 adjacent the front is provided with a depending portion 9 on the bottom so that when the cabinet is placed on a table, counter or the like. as shown in Figure 5, the depending portion 9 will be located normally in front of the support for the purpose of removably supporting on the cabinet 9. collecting unit l0.

' is mounted on the door 6 and is manually opthe present invention, as well as the feed mechanism for advancing the ice to the cutting mechanism.

Figure 4 is .a fragmentary top plan view illustrating the means of adjusting the cutting mechanism.

Figure 5 is a vertical sectional view illustrating the device.-'

Figure 6 is a transverse sectional view illustrating the knives of the cutting mechanism erated from the exterior of the cabinet for the purpose of shaving ice from the block of ice arranged'within the cabinet or for chipping ice from the block of ice if desired so that the cut ice may gravitate into the depending portion 9 and then into the collecting unit In. The collecting unit I0 is provided with front and rear compartments l3 and I4 separated from each other by a partition I 5. The upper ends of the compartments communicate with an opening l6 provided one compartment and the chipped ice to be directed into the other compartment of the collecting unit Ill.

Thegate I1 is carried b a shaft l8 journaled in the depending portion 9 and extends exteriorly thereof and is provided with an operating handle I9 whereby the position of the gate may be changed at the will of the operator.

The bottom wall of the depending portion 9 has angularly related flanges 20 to be engaged by flanges 2| of the collecting unit l so that the entire collecting unit may be applied and removed from the cabinet at the will of the operator.

The compartments l3 and [4 are separable from the remaining construction of the collecting unit so that they as a unit may be removed from the collecting unit after the detachment of the latter from the cabinet and carried from place to place for the purpose of dispensing the cut ice from the. compartments at a desired place.

A discharge spout 22 is integral with the compartments and common to both. The discharge spout 22 is controlled by swingable gates 23 carried by arms 24 one of which is integral with the shaft 25 and the other integral with a sleeve 26 journaled on the shaft 25. The shaft 25 is journaled in opposite walls of the compartments and the sleeve 26 extends along with the shaft 25 beyond one of the walls of the compartments and has secured thereto operating handles 21 oppositely disposed to each other, as shown in Figure 8, whereby the operator may swing either of the gates for opening either of the compartments to the discharge spout.

The movement of the arms 24 by the operating handles 21 will bring about agitation of the cut ice within the compartments to prevent the l2 as the shaft 33 is rotated in one direction. It is preferable that the bottom wall I l of the cablnet be provided with ribs 34 to support the block of ice from full contact with the bottom wall and thereby permit water melted from the ice to readily flow away from the block of ice and into the depending portion 9 resulting in less melting of the block of ice.

The shaft 33 extends at one end exterior of the depending portion 9 and has secured thereon a ratchet gear 34. Also journaled on said end of latter from massing and failing to flow freely to the discharge spout.

The bottom wall of the compartments on which the discharge spout 22 is formed is arcuately curved and the gates 23 are curved accordingly so as to match the curvature ofthe bottom wall. The bottom wall of the compartments has drain grooves 30 leading to the spout so that water may drain from the compartments to the discharge spout when the gates are in closed position to prevent excessive accumulation of water in the compartments along with the cut ice. 1

To prevent the water dripping from the spout 22 spilling onto a floor or the like, the lower portion of the collecting unit I0 is in the form of a skeleton frame and has removably mounted therein a tray or pan 3| located directly under the discharge spout 22 and spaced sufficiently far enough therefrom to permit various types of containers or receptacles to be placed under the discharge spout and within the pan or tray in order to obtain the ice from either of the compartments l3 or l4. A false bottom 32 is arranged in the pan or tray and is of foraminous material on which the different types of containers may rest and be kept from being positioned within the water caught in the pan or tray. The pan or tra is easily removable from the collecting unit l0 so that it may be emptied when need may occur. y

A feed mechanism shaft 33 is journaled in the depending portion 9 of the cabinet and is arranged transversely of the cabinet under the bottom wall ll thereof which protrudes partly over the depending portion and has secured thereto a plurality of spiked wheels 33' that extend through slots provided in the bottom wall H of the cabinet to bite into the block of ice so as to slide the block of ice toward the cutting mechanism the shaft is a hollow hub 35 of a hand lever 36. The hollow hub encloses the ratchet gear and has pivotally mounted therein a dog 31 engageable with the teeth of the ratchet gear under the influence of a spring 38. One end of the dog 31 is engaged by a cam 39 carried by a pin 40 journaled in the hub and extends exteriorly.

thereof and is provided with a finger piece 4| whereby the operator may disengage the dog from the ratchet gear 34' whenever it is desired for the hand lever 35 to move free of the feed shaft A lip 4| is formed on the hub 35 and has connected thereto a coil spring 42 which is suitably secured to the wall of the cabinet. The purpose of the spring 42 when tensioned is to swing the hand lever in one direction and when the dog 31 is in engagement with the ratchet gear to bring about rotation of the shaft 33 and thereby feed the block of ice to the cutting mechanism. The purpose of the hand lever 36 is to tension the spring 42 and to govern the movement of the hand lever 35 by the action of the spring 42, a friction brake 43 is adjustably secured to the free-end of the hand lever and drags against one wall of thevcabinet 5. The friction brake 43 is in the form of a disc 44 which contacts the wall of the cabinet, a shank 45 threaded in the hand lever and provided with a finger piece 46 whereby the pressure of the disc 44 against the wall of the cabinet may be varied by threading the shank 45 in opposite directions in the hand lever. The

anism. This, to some. extent, will bring about a variance in the cutting action of the cutting mechanism on the block of ice so that larger or smaller chips may be obtained or a greater or less amount of ice shavings.

The entire cutting mechanism I2 and its operating means is mounted on the inner face of the door 6 so that when the door is in an open position the cutting mechanism is disposed entirely outwardly of the cabinet. This will facilitate the placing of a block of icein the cabinet.

Secured .to and spaced from the inner face of the door 6 is a wall 41. The space provided between the door and the wall 41 accommodates a drive gear 48 secured on a shaft 49 journaled in the wall 41 and the door and extends beyond the outer face of the door to which is secured a crank handle 50. Journaled in the space between the door and the wall 41 and above and below and in mesh with the gear 48 are gears 5|, the shafts 52 thereof being equipped with against pins 68 carried by the frame 60.

Upper and lower transversely arranged chan 'nel tracks 56 are secured to the wall 41 and are engaged by rollers 51 journaled on stub shafts 58 secured to angle iron brackets 59 secured to the upper and lower portions of .the cutting mechanism l2. This construction will permit thecutting mechanism to reciprocate transversely of the cabinet at one end of the block of ice with a minimum amount of friction by the drive mechanism.

The cutting mechanism l2 includes a substantially rectangular shaped frame 60 secured to the angle iron brackets 59 and when the door is in a closed positionis supported at one end of the J ournaled in the frame and arranged vertically is a plur'ality of knife shafts 64 which extend through notches provided in the partitions and have journaled thereon hubs 65 of knife blades 66. The knife blades mounted on each shaft are all integral with a single hub which is journaled on the shaft. The free ends of the knife blades are sharpened and beveled to form cuttingedges. The hubs are secured to the shafts 64 and connected to said shafts are springs 61 that bear The action of the springs. 61 is to urge the free ends of the blades outwardly of the frame for contact with the end of the block of ice between the partitions so that the knife blades willact upon the ice between the scored lines formed bythe teeth 62 of the partitions of the frame. The knife blades'extend at an angle outwardly of the frame between the partitions, so that their free cutting edges will act to cut the ice on the movement of the frame in one direction relative to the end I of the block of ice and to move freely over the block of ice when the frame moves in a reverse direction.

Therefore, it will be seen by the rotation of the crank handle 50, the knife blades will be made to either shave ice particles off of the end of the block of ice or by adjusting the action of the knife .blades through a suitable adjusting means, which will be hereinafter more fully described, may be made to cut the ice into larger particles so as to produce a sort of crushed ice. By having the gate II, the operator'can direct the pulverized ice into one of the compartments of the collecting unit while the crushed ice may be I directed into the other compartment.

The shafts 64 of the knife blades 66 are provided with pins 69 engaged by a plate 10. The

plate I6 is slidable on top of the frame 66 and against the pins 69. The plate In isarranged at the-upper end of the frame and has attached thereto rods II extendingthrough openings provided in angle iron plate 59 and secured to plate I2. During the reciprocation of the knife frame 60 the plate IO-moves therewith, also rods II, and the plate I2. However, the plate I2 may be made to slide toward and from the frame 60 with plate'lll having a relative movement on top of frame 60 and the rods 'Il being fastened thereto will cause the pressure plate III to act on the pins 69 for either extending or retracting the (a knife blades with respect to the frame 60 to govern the depth of cut the knife blades will make in a block of ice to either produce large particles of ice or the fine particles.

The operating plate I2 is provided with a slot I3 in which-a squared portion I4 of an operating rod I5 engages. Collars I6 are secured on the operating rod I5 and spaced to engage opposite faces of the operating plate I2, still permitting the'operating plate to have sliding movement with the cutting mechanism relative to the operating rod I5 which is journaled in the wall 41 and the front door, the outer end 0f which is provided with a finger piece I6 whereby the operating rod 15 may be operated. The finger piece I6 is threaded onto the operating rod I5 and bears against the outer face of the door 6. By rotating the finger piece I6 in opposite directions on the operating rod I5, the latter will be allowed to slide in opposite directions bringing about a sliding movement of the operating plate I2 in opposite directions which in turn causes the plate 70 which is secured to plate I2 by rods It to act on the pins 69 of the knife shafts in op posite directions to extend or retract the knife blades relative to the end of the block of ice, thereby regulating the depth of cuts made by the knife blades between the score lines on the block of ice to produce either the pulverized ice. shavings or chips of ice. The deeper the knife blades cut into the block of ice during theirreciprocation relative thereto the larger the particles of ice will be cut from the block of ice. The less the knife blades cut into the, block of ice the smaller will be the particles ofice cutfrom the block of ice.

A signal member is pivotally mounted on latter and allows the signal member to move upwardly into signaling the amount of ice in haustion.

position indicating that From the foregoing description taken in connection with the accompanying drawings, it will be seen that a very practical machine is provided for cutting ice in block form into either extremely small or pulverized particles or into chips and that means is provided for the collection of the differently cut ice into separate compartments of e a collecting unit, which compartments are of integral construction and can be readily separated from the machine and carried from-one place to another.

of the collecting unit are equipped with means for dispensing the different cut sizes of icethrough a common discharge and at the same time agi- Further, it will be seen that the compartments tating the cut ice within the compartments. It i may not always be desirable that the compart- 'ments be removed from the collecting unit and carried from place to place and when not removed they may remain in the collecting unit and different types of containers. may bearranged on the tray 3! under the discharge spout to receive the cut'ice. All of this can be easily and quickly carried out with a minimum amount of manual effort without the operator coming in direct contact with the ice. The only humangcontact with the ice is necessary when placing theblock of ice within the cabinet which can be easily accomthe cabinet is nearing ex.-'

plished due to the fact that the door and the cutting mechanism carried thereby can be swung of will not interfere with the placing of the block of ice in the cabinet, the dog 31 may be freed of the ratchet gear 34 allowing the shaft 33 to rotate freely with the block of ice during its sliding movement into the cabinet.
